Engineering and Technology Journal, 2013, Volume 31, Issue 10, Pages 1982-1999

The project is an integrated system which is placed inside a vehicle for the purpose of tracking it to determine its current GPS location in the real time, the system use Global System for Mobile communication (GSM) network as a medium to send the information to a monitoring station in two way: the first way by using Short Messaging Service (SMS) while the second way use General Packet Radio Service (GPRS).The tracking system consist of two general units, the first unit is Vehicle unit and the second is the Monitoring unit. The main components in vehicle unit is the microcontroller (PIC18F452) which is the main part to control all operation in the vehicle starting with read GPS information and the vehicle status ending with sending the collected information to the monitoring unit through the wireless GSM, the second important component is the IC (GM862-GPS) which is a GSM modem, the PIC interfaced to GM862-GPS serially via RS232 interface protocol, so the PIC inquire GPS information from GM and command the GM to send the information to the monitor. The monitoring unit is a Laptop with a Universal Serial Bus (USB) GSM modem connected to it in order to send and receive information to/from GSM network. The information received from the vehicle will be displayed on a Graphic user interface (GUI) designed by Visual Basic (VB), the GPS of the car will be displayed on a Google earth map.

Recently LED display panels are widely used throughout the world in all situations to create images for visual displays in a variety of applications including communication and visual display devices. LED array display board is a popular instrument for commercial usage. Many banks, shops and cinemas are willing to install one piece of it because of its versatility. LED array display board can be very bright and eye-catching. A display sign used for advertising or for displaying direction or other information to motorists has an important feature in common. This research provides an efficient and scalable approach to LED Dot Matrix displays. The system is comprised of a tricolor dot matrix display panel with an interface circuit to a computer. It also comprises an executive program that runs on the computer for the display control of characters, decorative pattern or messages. The display board shows any character entered from the host computer which is interfaced using USB to a microcontroller that initializes the led driver. The advantage of this research is that size of the display board can be increased row wise and column wise without making any changes in the circuitry since display board is the repetition of a small independent module.
